Beyond Geometric Complementarity: Coherent Overlap in Sparse Mixture-of-Experts Routing

Huiyuan Tian, Bonan Xu, Shijian Li

Sparse mixture-of-experts (MoE) language models route each token to multiple experts, suggesting a geometric account of their benefit: co-selected experts should contribute distinc…

Distillation Dynamics: Towards Understanding Feature-Based Distillation in Vision Transformers

Huiyuan Tian, Bonan Xu, Shijian Li

While feature-based knowledge distillation has proven highly effective for compressing CNNs, these techniques unexpectedly fail when applied to Vision Transformers (ViTs), often pe…

From Per-Image Low-Rank to Encoding Mismatch: Rethinking Feature Distillation in Vision Transformers

Huiyuan Tian, Bonan Xu, Shijian Li

Feature-map knowledge distillation (KD) transfers internal representations well between comparably sized Vision Transformers (ViTs), but it often fails in compression. We revisit t…

SpectralKD: A Unified Framework for Interpreting and Distilling Vision Transformers via Spectral Analysis

Huiyuan Tian, Bonan Xu, Shijian Li +1

Knowledge Distillation (KD) has achieved widespread success in compressing large Vision Transformers (ViTs), but a unified theoretical framework for both ViTs and KD is still lacki…

Multi-Depth Branch Network for Efficient Image Super-Resolution

Huiyuan Tian, Li Zhang, Shijian Li +2

A longstanding challenge in Super-Resolution (SR) is how to efficiently enhance high-frequency details in Low-Resolution (LR) images while maintaining semantic coherence. This is p…
